iii 17 4[ JJ INVENTOR 62A, ez ge r ATTORNEY Patented Mar. 11, 1930 UNITED STATES GUSTAVE A. HETZGER, OF BELLEVILLE, ILLINOIS AIR-COOLIN G APPARATUS Application filed May 31, 1928. Serial No. 281,840.

This invention relates to air cooling apparatus designed to-be placed in openings in dwellings or otherbuildings such as windows,

or doors, the air passing through said open ings being cooled thereby.

A primaryobject of the invention is to provide an apparatus of this character which may be removably mounted in a window or door opening and so set as to ensure rapid evaporation of the air passing therethrough.

Another object is to provide apparatus of this character composed of a plurality of adjustable elements formed of liquid absorbing material and which are so mounted as to be opened or closed at the will of the user, and

to which may be supplied greater or less quantities of liquid, as may be desired.

Another object is to construct an apparatus of this character which will present an attractive appearance, and operates not only to cool the air but to filter out all dust which may be in the air entering through the apparatus.

In carrying out these objects, the invention is susceptible of a wide range of modification without departing from the spiritor sacrificing any of the advantages of the-claimed invention there being shown in the drawings for illustrative purposes a preferred and practical form, in which:

Figure 1 is a perspective view of the apparatus shown applied, parts of the apparatus and parts of the'window being broken out for convenience in illustration;

Fig. 2 is a detail top plan view of the apparatus; I I

Fig. 3 is an enlarged detail showing the water supply tank in transverse section and the other parts in side elevation;

Fig. 4 is a detail perspective view of one of the pins used in supporting the strips constituting a part of the invention, and

Fig.. 5 is a similar view showing a portion of one form of liquid supply means used in connection with the invention.

In the embodiment illustrated, a breast rail in the form of a trough 1 is shown mounted midway the window frame, preferably opposite the upper rail of the lower sash, as is shown clearly in Fig. 1, while a drip pan 2 is supported on the window sill by any suitable means. Leading from the trough-like container 1 at the bottom thereof, are a plurality of discharge pipes or nipples 3, provided with control valves 4 for regulating the amount of liquid to pass through said pipes. The. pipes 3 below the valves 4 are each provided with an annular collar 5 between which and the valve 4 the strip supporting pins 10 are designe to be mounted, which will be presently more fully described. Below the collar 5, the pipe has a nipple 6, through which the liquid from the tank or trough 1 .is designed to pass onto the absorbent fabric strips 20 which constitute a part of the cooling apparatus. 7

In the form shown in Figs. 1 and 3, these discharge pipes 3 are screwed into the bottom of the tank 1 at intervals, and the tank may be supplied with liquid to be used, preferably water, in any suitable manner.

In Fig. 5, the tank 1, which corresponds to the tank 1 of the figures above referred to, has a supply pipe 30 located therein, and from which the discharge pipes 3 also extend through the bottom of the member 1 which constitutes the breast rail of the window frame and covers this supply pipe, to present a more attractive appearance. In Fig. 5 only one discharge pipe 3 is shown, but obviously a plurality are to be used 'according to the fabric strips employed in the construction of the apparatus, and which are to be hereinafter more fully described.

.This pipe 30 may be connected with a water main, or any other source of water whereby water under pressure will be supplied to the pipe 30 for discharge through the branch pipes 3 to the fabric strips 20.

hese'strips 20, any desired number of which may be employed, according to the width of the strips and the width of the window in connection with which the apparatus is to be used, are to be made of a length corresponding to the opening in which the cooling'apparatus is to be mounted, and at their upper ends are equipped with attaching pins 10 similar to pins used in hanging draperies to provide for the renewal of the strips 20 when found necessary. The top bar 11 of each of these pins has a loop 12 formed preferably midway thereof, which is designed to encircle the neck of the pipe 3 below the valve 4: and between it and the collar 5, as is shown clearly in Fig. 3, and by means of which the pins are supported on these pipes with the nipples 6 arranged directly over the strips so that the liquid passes through them to the drip pan.

Extending laterally from one end of the upper bar 11 of the pin 10 is an arm 13 prov1 ed at its free end with an eye 14 with which is designed to be engaged a connecting rod 15 whereby all of the pins 10 are connected to operate in unison on the shifting of the bar 15. This bar 15 has one end thereof connected with an operating rod 16,

the upper end of which has an L-shaped arm 17, the free end of which is connected with the rod 15, as is shown clearly in Fi 1, the rod 15 and the arm 17 being prefera ly provided with interengaging eyes to accomplish this connection.

The rod 16 is designed to be arranged in upright position, and is provided at its lower end with an L-shaped arm 18 extending laterally therefrom, and which is connected with a rod 35. This rod is connected with a plurality of pins secured to lower end of the strips 20. These pins 40 also have laterally extending arms 41 with which the conneotin rod 35 is engaged. The lower members o the pins 40 are provided with eyes 42 through which are passed cross bars or rods 43 arranged transversely of the drip pan 2 and which operate to hold the lower ends of the strips 20 in proper relation to the dri pan so that the water dripping from sai strips will be caught by the pan.

The operating rod or bar 16 is provided in.- termediate its ends with a laterally extending finger grip or lever shown in the form of the loop 19 whereby said rod. 16 may be. operated to shift the connecting rods 15 and 35 longitudinally for opening and closing the strips 20. These strips 20 may be composed of any suitable absorbent material either canvas or other fabric which will have a capilla attraction for water, and they are prefera ly so arranged so that their adjacent edges overlap whereby when in closed position, they will-effectively shut out all draft, insects or the like.

The apparatus constructed as herein shown and described may be readily detached and placed in an out-of-the-way position when not desired for use.

From the above description, it will be obvious that when the apparatus is mounted as shown in Fig. .1 and water supplied to the breast rail 1, that the opening-of the valves 4 the desired extent will permit the water to drip down onto the fabric stri s 20 and pass by capillary attraction throng out the stri s thus exposing these dampened strips to t e entering air which will evaporate the water and enter the room in a cooled condition.

The swivelled mounting of the strips 20 provides for them being positioned at any desired angle so as to let more or less air pass between them and ensure rapid evaporation.

Without further description it is thought that the features and advantages of the 1nvention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention or its scope as claimed.

I claim 1. An air cooling apparatus comprising a water supply trough having a plurality of valved discharge pipes extending therefrom, pins 'detachably mounted. on said pipes, absorbent fabric strips carried by said pins, a
